无法使用k8ssandra部署Cassandra

Question

我使用下面的图表将Cassandra集群部署到我的gke集群中。https://github.com/k8ssandra/k8ssandra/tree/main/charts/k8ssandra

但是，状态集停留在状态1/2 ( cassandra容器状态总是不健康的)

这是我的values.yaml

cassandra:
  auth:
    superuser: 
      secret: cassandra-admin-secret
  clusterName: cassandra-cluster
  version: "4.0.0"
  cassandraLibDirVolume:
    storageClass: standard
    size: 5Gi
  allowMultipleNodesPerWorker: true
  resources:
    requests:
      cpu: 500m
      memory: 2Gi
    limits:
      cpu: 500m
      memory: 2Gi
  datacenters:
  - name: dc1
    size: 1
    racks:
    - name: default 

stargate:
  enabled: true
  replicas: 1
  heapMB: 256
  cpuReqMillicores: 200
  cpuLimMillicores: 500

kube-prometheus-stack:
  enabled: False

NAME                                                READY   STATUS     RESTARTS   AGE
cassandra-cluster-dc1-default-sts-0          1/2     Running    0          77m

然后我描述了这个吊舱

Events:
  Type     Reason     Age                    From     Message
  ----     ------     ----                   ----     -------
  Warning  Unhealthy  2m11s (x478 over 81m)  kubelet  Readiness probe failed: HTTP probe failed with statuscode: 500

最后，我打印cassandra容器的日志。

INFO  [nioEventLoopGroup-2-2] 2022-04-20 11:09:35,711 Cli.java:617 - address=/10.12.11.58:51000 url=/api/v0/metadata/endpoints status=500 Internal Server Error

和server-system-logger的日志

tail: cannot open '/var/log/cassandra/system.log' for reading: No such file or directory

我该如何解决这个问题？谢谢。

cassandra容器中的消息说，一旦Cassandra启动并运行，它应该自行解决，这是正确的。

类似地，在Cassandra启动之前，以及更准确地说，直到日志框架初始化之后，server-system-logger容器才可用日志。
